I am growing one plant of OG KUSH AUTO strain from Nirvana with light setup of 300watt of led grow light. What should be the distance between light and plant during various phases of seedling,vegetative, flowering?
I am using soil as grow medium.
I also run a 300w LED. For me it was:
Seedling: 30"
Veg: 24"
Preflower: 22"
Flower: 18"
You'll have to see how they respond, but this should give you some guidelines.
18 to 24 inches should be safe enough for seedling stage. If the seedling stretches too much, reduce the distance, then let the plant "grow" into the light.
